Intel AC 3168 won't connect to 5GHZ "N" router any faster than 150. Other devices connect at 300 (or 450 with certain hardware) to same router. Internet connection slows to unusable pace.

ASRock ITX board with built in Intel AC 3168. Two antennas which I assume means it has two channels and could do N 300. AC seems OK, but I need to use N at times.

1. The AC 3168 is capable to work in this speed. The max speed for 802.11ac WiFi connection is 433 Mbps. Your router should be set to 80MHz channel band width (for example channels 42, 58, 106, 122, 138, 155)
2. The AC 3168 has two antennas: one is used for 5 MHz WiFi and the second for 2.4MHz WiFi + BT.
